Daiki is a PhD student at the Hiroshima University, Japan, working on neutral mesons measurement in pp and Pb-Pb collisions. In 2013, during his Masters course, he joined the ALICE PHOS (PHOton Spectrometer) group. PHOS is a high-resolution electromagnetic calorimeter, mainly dedicated to the search for electromagnetic signals from the quark-gluon plasma in nucleus-nucleus interactions at high energies. During the Long Shutdown 1 (LS1) Daiki tested PHOS modules with a new readout system, called Scalable Readout Unit (SRU), in order to optimize PHOS mapping and digitization of signals from a photon sensor, and developed software to configure PHOS properly. Today he is in charge of operating the readout system of the PHOS detector.

In the beginning of the year Daiki was invited to be run manager. His first shift as such he took in the beginning of July. “Before joining the team in the control centre, I was only familiar with my detector and not so much with the central systems. Now I already know how to coordinate the experiment. It is complicated, but also very interesting, I really enjoy it. My first week was already full of events. Except for the usual technical operations, we had to assure access to the magnet two separate times and we also had to deal with a power glitch. I had to call all the detector experts and to ask them to check their systems, while keeping the experiment in a safe state. Fortunately, we have very clear instructions on what to do in a case of a power glitch, so we resolved the problem as quickly as possible.”

While serving as run manager, Daiki has the opportunity to communicate with people from all ALICE detector groups and he sees that as a big asset. “So far I have been working only with people from my group, but now I finally feel like a real member of the Collaboration.”

Daiki is really passionate about physics and he doesn’t take a break from enriching his knowledge even in his free time. “Being a PhD student means that I dedicate most of my time to the analysis. Still, when I have some time for myself, I like to read physics books. I also like to play tennis. It is fun and I enjoy it, but I only do it when I am back home, in Japan.”
